Core i9-12900KS vs Ryzen 9 7940HX comparison

According to the hardwareDB Benchmark tool, the Ryzen 9 7940HX is faster than the Core i9-12900KS. Despite this, the Core i9-12900KS has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores but the Ryzen 9 7940HX has more threads. With our hardware info, we find that the Core i9-12900KS has a slightly higher clock speed than the Ryzen 9 7940HX. Also, the Core i9-12900KS has a slightly higher turbo speed. The Ryzen 9 7940HX outputs less heat than Core i9-12900KS thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i9-12900KS has more threads than cores. Each physical core is split into multiple threads.
